**Component Type:** Program

Overview
========

``CProgIODemux`` routes one notify-capable input to one selected output. A
scalar ``uint32`` control IO selects the active output with zero-based indexes.
On start the input value is written to the selected output. Non-selected
outputs retain their previous values.

Configuration
=============

Kconfig

- ``CONFIG_DAWN_PROG_IODEMUX``: enables the program.
